miniDSP Introduces World’s Smallest Dirac Live Hardware Processor

July 20 2016, 04:00
miniDSP introduced the DDRC-24, a USB DAC+DSP Digital Room Correction processor powered by Dirac Live, featuring Toslink, analog inputs and up to 4 processed outputs for 2.0, 2.1, or 2-way active speaker configurations. With the smallest Dirac Live hardware processor miniDSP is making room correction even easier and more affordable, perfect for tuning hi-fi listening rooms, subwoofer integration, tuning mobile applications and adjusting monitors in recording studios.
 

The new miniDSP DDRC-24 is now the world’s smallest Dirac Live hardware processor, making room correction available in a compact hardware unit. Powered by a 400 MHz Analog Devices SHARC processor, the DDRC-24 retains the 4-channel output of its sister unit, the miniDSP 2x4 Hd, in order to allow applications like subwoofer integration or even 2-way loudspeakers together with Dirac Live room correction in a single hardware platform. The matrix mixer and crossover functionality is accessed and programmed with miniDSP’s easy-to-use interface software. 

This all in one unit with USB DAC + Dirac Live Room Correction + Speaker processing now also offers improved I/O capabilities with the addition of USB audio streaming up to 192 kHz and a Toslink digital input. The DDRC-24 features the XMOS Xcore200 processor for USB control and bidirectional audio streaming, 24-bit ADC/DAC conversion, unbalanced inputs switchable with a jumper between 4Vrms and 2Vrms, and unbalanced outputs (max 2Vrms). The unit supports USB Audio Class 2 bidirectional streaming with ASIO drivers on Windows and driverless under MacOS X.

The Dirac Live for miniDSP software features 4 presets with fully configurable target curve, recallable also via infrared remote. Internal processing is 32-bit with 48kHz sample rate. The optional UMIK-1 measurement microphone is required for performing acoustic measurements when using the Dirac Live software.
 

miniDSP has teamed up with Dirac Research to launch the miniDSP Dirac Series in 2014, creating a unique hardware and software combination that includes everything an audio enthusiast will need to acoustically capture a listening room, generate optimized room correction filters, and deploy them in the listening room. By simply inserting the miniDSP Dirac Series audio processor in the audio signal chain and utilizing the customized Dirac Live Calibration Tool together with the included UMIK-1 microphone, users can perform multi-point measurements in their listening room, using a series of visuals for microphone placement. In-room target curves can be designed and an optimized set of digital room correction filters can be generated and loaded back into the audio processor.

Dirac Live is a powerful room correction algorithm developed by Dirac Research AB of Sweden, using a set of measurements taken around the listening area to generate a correction filter. By independently correcting in time as well as frequency domains, miniDSP Dirac Series audio processors affect the impulse response enabling improved imaging and clarity, tighter bass and reduction of room resonances, elimination of early reflections, and reduced listening fatigue. Once configured, the miniDSP DDRC-24 does not require a computer anymore as all settings are stored in memory and are automatically reloaded at each boot-up.

The miniDSP DDRC-24 includes not only Dirac Live but also a full set of crossover functions on its four output channels. One use of this is as a flexible tool for integrating subwoofers into any system along with Dirac Live. The hardware device can also be used together with the Room EQ Wizard (REW) software to equalize the connected speaker configuration. A useful addition to any listening environment or basic home theater, in cars, in recording studios, or anywhere a compact, powerful room correction processor is needed.
